srAnK INTENSIFIER.

Application filed. December 12, 1921. Serial No. 521,803.

- which the following is a specification.

My object is to provide a spark intensifier of superposed elements adapted to be easily assembled and separated to facilitate manufacture, inspection and repairs, and a further object is to provide a simple form of spark intensifier which will be inexpensive to produce and convenient to attach and use in connection with the spark plugs of internal combustion engines.

In the accompanying drawing, Flg. 1 is a side view of my improved spark intensifier attached to a spark plug. Fig. 2 is a plan view of the spark intensifier, and Fig. 3 is a longitudinal section thereof on line 3-3 of Fig. 2. Fig. 1 is a plan view of the spark intensifier opened to give free access to the sparking elements. Figs. to 9 inclusive, are perspective views of the scparateelements composing the device.

The invention comprises three separate flat pieces of fiber, 2, 3 and respectively, superposed and fastened together at their corresponding ends by a rivet 5, or its equivalent. All said three pieces possess separatetentral openings adapted to register with each other to provide a common air passage, and the opening 6 in piece 1 is of smaller diameter than the openings 7 and 8, respec tively, in pieces 2 and 3, to induce a slight flow of air through the openings. The'bottom face of piece 2 is provided with atapered stepped channel 9, extending from opening 7 to one end edge thereof, and

7 channel or recess 9 is adapted to receive and confine a flat metal conductor 10 having a raised sparkin point 11 at its inner and slot or opening 17 adjacent central opening 8. A second metal conducting element 18 of tapering form longitudinally and offset at its smaller end '19, is adapted to occupy recess 16 in piece 3, the offset end 19 being projected through slot 17.into central openv ing 8 where the raised sparking point 20. thereon is held in closely-spaced.relation to the sparking point 11 on conductor 10. The

outer end 21 of conducting element 18 is perforated to facilitat-e the attachment of an electric wire or conductor thereto, and both of the conducting elements 10 and 18 have openings at their middle adapted to receive the round bosses 22 and 23 located centrally in channels 16 and 9, respectively. Rivet 5 passes through boss 22 and a screw 2e extends through piece 2 and its boss 23 I and through middle piece 3 and into piece 4.- to fastenand clamp the parts together when assembled as shown in Fig. 3.

In use when this device is applied to a spark plug, the electric current in passing to the plug jumps the gap between points 11 and 20 and creates a stronger and more in- .sults after continued use of the device it is also desirable to clean and brighten the op-- posing points at intervals. I facilitate ad justments and bending of the points towards and away from each other, and give free access to the points, when screw 24- isremoved to permit the separate pieces to swivel or turn on pivot pin 5 into an open position.

substantially as shown in Fig. 4:. In this position of the parts, conducting elementlO can be bodilyvremoved if desired.

That I claim, is

A spark intensifier, comprising three superposed flat pieces having central registering openings and two of, said pieces having stepped channels in their meeting faces, separate metal conductors having offset ends provided. with sparking points extending into. said central openings, and means pivotally uniting said pieces together.

In testimony whereof I afiix my signature.
